Flask/Django modules of converting files [duplicate]
I'm trying to build a little converter website. pdf to docx, images to pdf, csv to excel etc... I really want to use node as my static files host server. But as I know node doesn't have that cool modules to handle such convertations. I think of using another server of python, e.g flask or django frameworks. So what are the best modules for python for converting files? Is there anything you could suggest me for solving this problem? -
Submit form with other modal forms Django
I'm trying to create an HTML page with a form, I have a button that open a modal with another form. The form within the modal is being submitted correctly but when I try to submit the other form the button doesn't send any request but I don't know why. I'm not very skilled using Django and HTML/JS so I could be missing something but I didn't have this problem on other pages. I'm also using crispy-bootstrap-forms. This is my HTML code: {% extends 'scenarios/home.html' %} {% load crispy_forms_tags %} {%block subtitle%} <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script> <h1 style="text-align:center"> Create your scenario </h1> {%endblock%} {% block body %} <div class="container"> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {{scenario_form|crispy}} <h1> VM List </h1> {%if vm_list%} <ul> {% for vm in vm_list %} <h3>{{vm.nome}}</h3> <span></span> <button> Edit Machine</button> {% endfor %} </ul> {% else %} <h2>No VMs at the moment</h2> {% endif %} <div class="container"> <!-- Trigger/Open The Modal --> <button type="button" class="btn btn-default btn-lg" id="myBtn">Add VM</button> <!-- Modal --> <div class="modal fade" id="myModal" role="dialog"> <div class="modal-dialog"> <!-- Modal content--> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">&times;</button> </div> <div class="modal-body"> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} … -

Multiple Choice with django
Im working on a quiz application with Django. Im struggling with making a form that can act as the multiple choice. I have to pull the questions and answers from the database so, i then display them on the page. I was going to just put booleanfield checkboxes beside the displayed choices, is there a better way to do this? I recently became aware of the multiple choice field, but i believe it aids in displaying the choice as well. I just want there to be 'boxes' i can customize with css. Is there anyway to have the field pull from the database or can i use the multiple choice field to display the wanted boxes by the answer choices already displayed. -

Django on Heroku. See all GET requests of a path
I have a Django 2.0 project hosted on Heroku. In the logs, this is what a GET request looks like: timestamp source[dyno]: message 2021-02-14T05:23:35.513467+00:00 heroku[router]: at=info method=GET path="/static/tag.gif"... I'd like to be able to access the full GET request message with python in the Django project. I'd preferably like to get this through the django-heroku library. If that's not possible, then I'd like some way to scrape the Heroku logs. I know they can be filtered by source and dyno via CLI, but I haven't seen anything about filtering by message. Maybe there's a way to add a listener of sorts? -
